SOUTH AFRICAN PEEISPORIACE^. 
II. Eevisional Notes.

(With three Text-figures.) 
In working through a number of fresh collections of South African 
Perisporiaceae, it has become evident that certain species described in my 
previous paper* on this group need revision. On p. 726 of the above- 
mentioned publication Meliola torta is described on the leaves of Trichocladus 
crinitus, and it is stated that there is another Meliola associated with this on 
the same leaves, with 4- septate spores and no setse, but this was badly 
parasitised and could not be determined. In examining fresh collections of 
fungi on the same host, it has become evident that some confusion has arisen 
owing to the fact that there are at least four fungi (possibly more) on the 
same leaves. 
One of these is an Aster ina ; of the others, in the first collection of 
Trichocladus the perithecia of Meliola torta were immature, and the spores 
of a fungus parasitic on the Meliola, and having similar perithecia, were 
described as those of Meliola torta. In later collections mature perithecia 
of Meliola torta were found with large 4- septate spores. It therefore 
becomes necessary to redescribe Meliola torta, and to describe the fungus 
parasitic on the two Meliolas. Mature non-parasitised material of the 
second species of Meliola was also found, and, as it appears to be a new 
species, I have named it Meliola scabra, on account of the frequently 
scabrous character of the capitate hyphopodia.
